Internet connection being a bit slow today, apparently, I've noticed some of the "Connecting to..." info in the bottom left of Firefox when visiting this site. Addresses of the type 1.2.3.x appear quite often. Searching around, I found that this has something to do with the APNIC debogon project, which lead me to this article. While this is written in superficially comprehensible English I'm still none the wiser. For example, it says that "filtering of unallocated address space... is a good thing." Really? Why? My understanding of things goes rapidly downhill after that.
Assuming I do understand it at all, won't IPv6 just makes things worse? There will be a vastly greater range of unallocated IP addresses to filter and with more blocks being allocated as ever more devices need unique IP addresses, ISPs and other network operators will find it ever harder to keep up with making new addresses route-able.
